1 What is Kerydin?

Brand: Kerydin

Generic: Tavaborole

Kerydin is an antifungal medicine used to treat onychomycosis, the fungal infection of the nails.

Current labeling only states that Tavaborole can be used only on onychomycosis of the toenails. Tavaborole belongs to the oxaborole class of antifungals. It works by inhibiting production of an enzyme in fungal cells, causing it to stop growing and die.

Onychomycosis is a common health problem and recurrence after treatment is not uncommon. Doctors prescribe Tavaborole to treat oncychomycosis caused by the fungi Trichophyton rubrum and Trichophyton mentagrophytes.

Tavaborole requires a prescription.

2 What to know before using

Before using Kerydin, you must know all about the risks and complications associated with it.

You cannot use Tavaborole if you are allergic to it.

Tell your doctor if you are pregnant or breastfeeding before receiving Tavaborole. Tavaborole may cause increased risk of harm to the unborn babies when used by pregnant patients. It is not well known if Tavaborole is expressed in breast milk, but for safety do not nurse when receiving the drug.

The safety of Tavaborole to children is not yet established.

3 Proper usage

To use Kerydin properly, you must follow all instructions given by your doctor.

Tavaborole is available as a solution for application on the affected toenails. The doctor or other health professionals will teach you to apply Tavaborole solution correctly.

Tavaborole is usually applied daily for 48 weeks.

Here are the step-by-step instructions in applying Tavaborole correctly:

  • Wash and dry the toenails thoroughly
  • With the provided dropper, apply the Tavaborole solution and cover the entire nail surface completely. Make sure to also apply under the tip of the nail
  • Allow Tavaborole solution to dry completely before wearing any footwear or sock
  • Wash hands after applying Tavaborole

Only apply Tavaborole on the affected nail. If you accidentally applied Tavaborole on the skin around the nail and other areas of the body, you can wash them with soap and water.

During treatment, the nail may start to look better, but the infection is not yet totally cleared. For best results, always use Tavaborole as prescribed.

If you missed applying Tavaborole, do it as soon as you remember. If I am almost time for the next application, skip the missed dose and stick to the original dosing.

Do not take Tavaborole solution by mouth. If this does happen, call local poison control hotlines for help.

Store Tavaborole at 20 C to 25 C. Keep the medicine away from heat or flame.
